Product Line Details

DFC GEOSPEC rotors are coated to resist rust better than conventional paint or zinc finishes, and they arrive dry so there is no need to clean off oil before installation. The 5000 Advanced brake pad line is formulated for stable friction performance and uses shims to help reduce noise, vibration, and harshness. Part number 4502-68030 is part of DFC Complete Brake Kits, which package matched rotors and pads for a rear brake service.
